HPMDA/1,2,4,5-Cyclohexanetetracarboxylic acid dianhydride cas:2754-41-8

Kufotokozera Kwachidule:

1,2,4,5-cyclohexanetetracarboxylic dianhydride, yomwe nthawi zambiri imafupikitsidwa ngati CHTCDA, ndi yoyera ya crystalline yolimba yokhala ndi mankhwala a C10H2O6.Amagwiritsidwa ntchito kwambiri ngati chomangira popanga ma polima ochita bwino kwambiri ndi utomoni.Mankhwalawa amapangidwa pogwiritsa ntchito maleic anhydride ndi cyclohexane panthawi ya okosijeni.

1. Mapulogalamu:

1,2,4,5-cyclohexanetetracarboxylic dianhydride imapeza ntchito zambiri popanga ma polima osagwira kutentha ndi utomoni.Imapereka kukhazikika kwamafuta, kutentha kwa magalasi apamwamba, komanso mawonekedwe apamwamba amakina, kupangitsa kuti ikhale chisankho chabwino pamapulasitiki, zokutira, zomatira, ndi zophatikiza.Kukhoza kwake kupirira mikhalidwe yoipitsitsa, monga kutentha kwakukulu ndi mankhwala owopsa, kumapereka ndalama ku mafakitale osiyanasiyana kuphatikizapo magalimoto, ndege, zamagetsi, ndi zomangamanga.

2. Ubwino:

Chifukwa cha mawonekedwe ake apadera komanso katundu, CHTCDA imapereka maubwino angapo odziwika.Choyamba, imapereka kukana kutentha kwapamwamba komanso kuchedwa kwamoto kuzinthu, kumapangitsa chitetezo ndi kulimba kwa zinthu zomaliza.Kachiwiri, kukhazikika kwake kwamatenthedwe kumatsimikizira kuti ma polima omaliza ndi utomoni amakhalabe osakhudzidwa ndi kutentha kwakukulu komwe kumachitika panthawi yokonza ndikugwiritsa ntchito.Kuphatikiza apo, mankhwalawa amawonetsa zinthu zabwino kwambiri zotchinjiriza magetsi, zomwe zimapangitsa kuti zikhale zoyenera pamagetsi ndi magetsi.

3. Zofotokozera:

The 1,2,4,5-cyclohexanetetracarboxylic dianhydride imapezeka mu mawonekedwe a granular, ndi mlingo wachiyero wa 99% kapena kuposa.Ili ndi kulemera kwa 218.13 g/mol ndi malo osungunuka pafupifupi 315.°C. Mankhwalawa ndi okhazikika m'malo osungira bwino ndipo ayenera kusungidwa pamalo ozizira, owuma kuti asunge umphumphu wake.

Pomaliza, 1,2,4,5-cyclohexanetetracarboxylic dianhydride ndi yosunthika komanso yamtengo wapatali yamankhwala yomwe imagwiritsidwa ntchito kwambiri popanga ma polima ndi utomoni wapamwamba kwambiri.Makhalidwe ake apamwamba, kuphatikiza kukana kutentha, kukhazikika kwamafuta, komanso kutsekemera kwamagetsi, zimapangitsa kuti ikhale yofunika kwambiri pamafakitale osiyanasiyana.Timakutsimikizirani zamtundu wapamwamba kwambiri, chiyero, ndi kudalirika pagulu lililonse la CHTCDA lomwe mumapeza kuchokera kwa ife.
